Cloud Case Sharing: Microsoft + HP =iaas Solutions

In the morning of December 2, 7, from Microsoft technical experts Zhang Wei and Hewlett-Packard technical expert Liu Dahuan shared a real customer case of cloud computing.

▲ HP Technical expert Liu Dahuan

It is described as an IaaS solution with a three-tier architecture built by Microsoft and HP that virtualization infrastructure resources and provide virtual resources to users in the form of Web services.

Development background: Three major dilemmas for existing IT systems

The solution addresses three problems with existing data centers: first, most IT systems are decentralized, inefficient, and difficult to centralize and effective management; Secondly, the new business needs a number of IT systems to coordinate, application development and coordination work heavy; Finally, chimney-style IT systems (including servers, storage, Basic software, application difficult to share. To solve the problem, Hewlett-Packard and Microsoft together to create an IaaS solution.

"Loosely coupled" three-tier architecture enables rapid scaling across data centers

To provide shared, standardized, and resilient services to customers, the IaaS solution employs a three-tier architecture, from bottom to top: the resource supply layer, the service delivery layer, and the business requirements layer.

▲ Three-tier architecture

The business requirements layer encompasses the release of services, consumer, management and monitoring performance by implementation, through service capabilities, service levels and service directory management, service providers to provide services to consumers, consumers through simple operation, through the submission of service requests to complete the service request; Use the service function to view and manipulate the virtual machine, And the use of the service can be viewed through account processing.

The service delivery layer transforms service requests into service orders through order management and delivers them to the service process management for processing. The service flow Management will arrange the order process according to the type of the order, and complete the order processing through the service guarantee. User Management module is responsible for the user and virtual machine permission settings, users manage their own virtual machines (including logins, sequel configuration changes, virtual machine logoff, and so on) through the sequel management function, and can also view virtual machine usage (including CPU, memory, hard disk, and network traffic) through virtual machine monitoring.

The resource supply layer is the lowest level of the three-tier architecture, realize the virtualization of IT resources and management control, through the resource supply and configuration across multiple data centers, through the efficient use of resource pools, based on and configuration of policy templates, to achieve virtual machine creation, start, stop, change, monitor, delete and other functions; You can dynamically allocate resources to automatically balance server load. The resource management module mainly manages the server, the storage, the network resources, realizes the automatic and the self-management resource pool and the resource management environment, and monitors the resources performance and the capacity. The resource supply layer is implemented primarily through Microsoft's System Center, through the System Center's four "King Kong": System Center Data homeowner Manager 2007, System Center Revisit Manager 2007, System Center Operations Manager2007 and System Center Virtual Machine Manager, together to achieve a dynamic expansion of resources, And you can implement a Cross-domain data center extension.

Functional parsing

In the speech, Liu Dahuan shared with the audience the process of implementing the important functions of the system and the related code.
